TOOLFEOR HOLDING SCREW-HOOKS, 80C.

SPECIFICATION formingrpart of Letters Patent No. 510,104, dated December5, 1893.

Application filed January 13, 1893. Serial 110.458.212. (No model.)Patented in France July 9, 1892, No. 222,893.

burg, Bavaria, Germany, have invented a new.

and useful Improvementin Bit-Stocks or Tools for Holding Screw-Hooks orLike Articles, of

which the followingis a full, clear, and exact 7 description, and forwhich Letters Patent have been obtained in France, No. 222,893, datedJuly 9, 1892.

My invention consists in the novel arrangement and combination of partshereinafter described and set forth in the claims.

Reference is had to the accompanying drawings, wherein- Figure 1 isaside view of my improved tool. Fig. 2 is a side view, partly in section,of the same attached to a screw-hook. Fig. 3 is an end view oftheimproved tool. Fig. 4 is a section on line 44 of Fig. 2. Fig. 5 is aside view showing the tool attached to a brace or bit-stock. Fig. 6 isaside view, partly in section, of the tool with a screw-driver bitapplied thereto. Figs. 7 and 8 show a device for screwing in andwithdrawing screw-eyes, and adapted to be held in said tool.

In inserting or withdrawing screw hooks, it has hitherto usually beennecessary to use flat pliers, or even cutting pinchers. Now, to make theuse of such instruments unnecessary, a tool, forming the subject-matterof this invention, has been designed, which may be handled easily andsafely, and is preferably used in conjunction with, or as a part of, ahand brace or bit-stock.

a. represents the stem of my improved tool, which stem is adapted to fitinto an ordinary crank brace and has a suitable head b. The head I) isprovided with a transverse slot d, into which a screw-hook c, or thelike, may fit, or in which a variety of tools, such as shown at k, l,are adapted to be introduced.

6 is a pressure plate, which is pressed from the under side by a coilspring f contained within the opening 9 of the head I). The plate e isheld vertically on the one hand by means of the surfaces, Fig, 4E,forming the sides of the head, and on the other hand by means of thescrew g, which fits into the part t' of the tool. A large variety oftools or bits can be employed in connection with my improved tool, bysimply providing them with hook-like ends, as shown in Figs. 2 and 7.

In order to put my device into use, say for withdrawing a screw-hook, itis merely necessary to force the pressure plate 9 back far enough toallow the hook to be inserted within the slot d, when the pressure platecan be released, allowing it to press upon and hold the hook inposition,as shown in Fig. 2. The brace can then be attached in the usualmanner and the screw-hook withdrawn. When it is desired to use any of avariety of tools, they are inserted and held in substantially the mannerabove described.

It will be seen that I, by my invention, not only provide a device forinterchangeably using a variety of tools, but also provide one which isadapted to withdraw screw-hooks, screw-eyes, &c.

Having described my invention, I claim 1. The combination, in a bitstock or tool, of the body with a head b, having a transverse bitreceiving slot 01 a portion of which extends into the head below thesurface thereof, and a spring pressed presser-plate e, operating in saidtransverse slot substantially as described, and for the purposes setforth.

2. The combination, in a bit stock or tool, of the body with a head I)having a transverse slot (1 therein, spring-pressed presser-plate e anda tool or bit having a projection at substantially right angles to theaxis thereof, which projection is adapted to fit within the slot d andbe held therein by the presser-plate e, substantially as described andfor the purposes set forth.
